Perhaps you should try some spelling variations:
"linac based level optimization algorithm" » "linac based global optimization algorithm" (Expand Search), "linac based based optimization algorithm" (Expand Search), "linac cased level optimization algorithm" (Expand Search)
"binary base capacity optimization algorithm" » "binary case capacity optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("binary base capacity optimization algorithm") OR ("linac based level optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary base capacity optimization algorithm\") OR (\"linac based level optimization algorithm\"))".
• Removing quotes may allow a broader search: (( binary base capacity optimization algorithm ) OR ( linac based level optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("binary base capacity optimization algorithm") OR ("linac based level optimization algorithm"))*.
